man, I built something pretty similar and had a great time with it. nice!Dr Tony Balls wrote: Mon Aug 15, 2022 10:58 am Slow couple of months there...
AB165 Bassman-style preamp. Customer is in love with the sound of his AB165 Bassman but needs something mass-transit friendly. He'll be pairing it with a pedalboard power amp (Quilter or the like) and have an all-in-one pedalboard rig that can connect direct to a cab. It reproduce the Bassman preamp with FETs in place of 12AX7 triodes, running at 18V off a standard 9V supply, with an added master volume. I tested it by plugging it in to the power-amp in on a Sunn Beta and it rips!
would love to hear samples!Dr Tony Balls wrote: Mon Aug 15, 2022 10:58 am Slow couple of months there...

Well, it arrived today and Tony really knocked it out the park! I jury-rigged together a way to test it as best I could from what I have in the house....

I'd say it has slightly less overdrive than the real thing but that's no doubt down to the fact it's just preamp drive and no power tube saturation. EQ is nailing it too. I think, certainly in a live situation, I don't think anyone in an audience would even notice. It sounds really, really good.
10/10 would recommend
